MSG® LMAC™ 30 Centrifugal Air Compressor

MSG® LMAC™ 30 Centrifugal Air Compressor

The MSG LMAC is an integrally geared centrifugal compressor that has been optimized for applications in air separation units (ASU) as the main air compressor (MAC). The compressor package is designed for ease of installation, operation and maintenance, and to comply with various design code requirements for global installations. The MSG LMAC is available in three models that have been aerodynamically optimized to serve as the MAC in ASUs producing 150 to 400 tons of oxygen per day (TPD).

Air Separation Process

The volumetric composition of dry atmospheric air is ~78% nitrogen and ~21% oxygen, with the remaining ~1% being made of argon, carbon dioxide and trace amounts of other gases. These gases can be separated in an air separation process where the air is compressed, cooled and separated by molecular weight in a “cold box.” Once separated, the gases are again compressed for storage, transportation, or further processing. Ingersoll Rand has the technologies and resources to provide the main air compressor (MAC), booster air compressor (BAC), nitrogen gas compressor (GAN), nitrogen recycle compressor (NRC), and argon gas compressors.

The MSG LMAC is designed specifically to fulfill the role of the MAC with optimized aerodynamic efficiency. Interstage coolers are implemented after each stage of compression to remove the heat of compression and achieve high isothermal efficiency. The MAC is the heart of the ASU; its efficient and reliable operation is critical to the success and viability of the ASU project.

Highly Efficient Design

MSG LMAC compressors are designed to deliver peak performance throughout the entire compressor operating range and feature:
